Dreadbox Abyss

4-Voice Analog Synthesizer

The Dreadbox Abyss is a 4-voice analogue synthesizer featuring four modes, one VCO and sub oscillator per voice, white noise, and is 15V DC powered. With all-analogue discrete components, this synthesizer offers four playing modes: Unison, Polyphony, Chords and Multi-Channel. The Chords mode features user chords in addition, whilst Multi-Channel also offers multi-timbral over selected controls. With an indpendent wave shaping modulator and polyphonic glide function, this synthesizer contains four independent LFOs (one for each voice) to control vibrato. With variable speed depth and delay, the vibratos can be set out of phase via the Detune control. A VCO AutoTune function is also included.
